This willprevent the person or object from being run over. Where two cars cometogether in this manner the front Wheels 7 .of each automobile will bedeflected, so that they will be-deflected in opposite directions,

i and thereby any injury produced will-be re duced to a minimum. As bothsides of the bumper are identical, it will be evident that the sameaction takes place in case the bump er is struck on the opposite side ornear the opposite side. Forinstance, if the bumper is struck aboutone-third the distance from pin 34 to pin 18, the deflector 32 willfunction to deflect the automobile in a given di rection, and the sameis tru'ewhen the deflector 32 is functioning. In case there is a directhead-on collision, the bumper will cushion theblow and usually produce arebounding action, as most parts of the bumper are. resilientand'mounted to spring or move. either pivotally or slidably to take careof different strains, The formation of the bumper with resilient ormoving parts results ma minimum mJury'When a person or artlcle isstruck,'and 1n case the person or art cle is struck near either end ofthe bumper, the

oncoming automobile will be deflected to one side. n a

What I claim is LA bumper, comprising a rigid bar,

; means for connecting said'bar rigidly to the chassis of an automobile,and a plurality of resilient bars carried by said rigid 'bar,.certain ofsaid resilient bars being movable boda v ily substantiallylongitudinally.

' 2. A bumper, including a rigid bar, a substantially V-shaped springpivotally connected witlreach end of said bar, a plurality of resilientbars connected to the outer ends of sald springs, said bars havlng frontpor-- .tions extending towards each other and rear portion-s pivotallymounted on said rigid bar,

and a connecting bracing spring pivotally i .mounted on said rigid barand slidably connected with said front portions 3. A bumper forautomibles, comprising a rigid bar,means for connecting said rigid barto the automobile, a plurialityof front bars, eachfront bar having abent section eXtending rearwardly and pivotally mounted on said; rigidbar, a spring pivotally connected atboth ends to said rigid barandformed with the center portion interlocking with said frontbarsfifor'holding the same in operating position, and end springs forconnecting said 7 frontbars with said rigid bar, each of said endsprings being formed with means. for striking a front wheel of theautomobile when pressed rearwardly, whereby the wheel will be tnrned'toone side for deflecting the course ofthe automobile. 44A bumper forautomobiles and similar vehicles, including arigid structure con-- sidewhen the bumper is struck near either end.

i 6. A bumper for automobiles, including a channel-shaped rigid bar,brackets for securing said bar to the chassis of an automobile, saidchannel-shaped bar having the side flanges extend at the ends beyond thecenter part of the bar, a pin extending through :each end of said bar, aswinging spring pivotally connected with said bar through said pins, apair of front bars, means for pivotally connecting said springs to saidfront bars, and a plurality of resilient members for resiliently holdingsaid front bars in a given position, said members being pivotallyconnected with said rigid bar.

7. A bumper for automobiles, including a supporting member, means forconnecting the same with the chassis of an automobile, a pair ofresilient front bars, each of said front bars having bowedresilient'extensions'pivotally connected with said supporting mem-- ber,a double looped spring carried by said supporting member, and a pair ofpins carried by said front bars for pivotally and slidably connectingthe front bars with said double bowed spring.

8. A. bumper for automobiles, comprising a stiff supporting bar, adouble bowed spring, a clamp for clamping the ends of the spring againstthe center of the bowed portion of the spring, a plurality of pairs offront.

resilient bars, a pin carried by each pair of bars, said pins extendingthrough the looped portion of said double bowed spring, and means forpivotally connecting the outer end of each of'said bars to saidsupporting bar,

whereby when pressure is brought to bear on the outer part of said frontbars, the same will bow and'also move longitudinally away from eachother.

9. A bumper, including a rigid supporting bar adapted to be connectedwith an automobile, a plurality of pairs of front contact bars normallyarranged parallel to said supporting bar, and a plurality of resilientmeans for connecting said front bars to said supporting bar.

' 10. A bumper, including a stiff supporting bar adapted to be connectedwith an automobile, a plurality of pairs of front contact bars, andresilient means for connecting said contact bflJ'SWith saidsupporting'bar, said resilient means being mounted-to permit saidcontact bars to slide transversely of the V automobile when pressure isbrought to bear thereon." \1

11. A bumper for automobiles,vincli1ding a a bar adapted tobeconnected'with an automobile, a pair of front resilient contact bars,

a substantially V-shaped'spring connecting one end of each of thecontact bars With said supporting bar, and a spring for normally holdingsaid contact bars in positionfsaidf spring having the ends'loo'ped, thelooped 7 portions being pivotally connected with said supporting barandthe center slidably con nected With said contacthars.
